An interesting question came into the weather center this
week; "This is something my grandmother used to swear by, and also my parents;
that in spring and fall the night of a full moon is more likely to have temps
drop below freezing. I have never done anything to prove this one way or
the other, but last night sure was a full moon, and it sure did freeze in a lot
of places! Do you guys have any hard evidence on this?"

The answer is there is no correlation between
the moon phase and frost. The thing is, frost tends to only form on clear
nights in the late spring or early autumn seasons, so the clear sky of course
gives people notice of the moon be it a full moon, quarter moon, gibbous moon
or waning moon, it doesn’t matter, it is the clear sky that is allowing for
cooler temps, not the moon phase.
